چکیده
We continue to derive spacetime quantities and spin 1/2 propagators from rotations. Rotation-invariant projection operators are found for each element of a four element basis, i.e. a basis for four component quantities with specific transformation rules under rotations. With these four projection operators, we make two spacetime invariant projection operators, i.e. once space, time, energy, and momentum are identified. The spacetime invariant operators are propagators for free neutrinos. Except for the substitute basis, the process is the same as the one that gave electron propagators in Part I.

Rotations and e , ν Propagators , Part III Richard Shurtleff
In Parts I and II we showed that e, ν propagators can be derived from rotation invariant projection operators, thereby providing examples of how quantities with spacetime symmetry can be obtained by constraining rotationally symmetric objects. One constraint is the restriction of the basis; only two kinds of bases were considered, one for the electron and one for the neutrino. In this part, we ...
متن کاملRotations and e, ν Propagators, Part I
Rotation symmetry is less constraining than space-time symmetry. The free electron propagator is a projection operator that we show can be constructed from rotation symmetric projection operators. Rotation-based identifications of time, space, energy, momentum, polarization matrices, and the positron hypothesis are determined by the constraints that turn rotation symmetric projection operators ...
متن کاملThe effect on the hadron propagators due to k μ k ν terms in the vector meson propagator
The effect on the hadron propagators due to k µ k ν terms in the vector meson propagator Abstract In an approximation where the baryon current conservation is violated , the contribution of the k µ k ν terms in the vector meson propa-gator may not vanish. Their effects on the baryon and meson spectral functions and on the consequences of self-consistency are studied in the relativistic self-con...

متن کاملTheory of Functions of a Real Variable I Remarks on the Proof of the Hahn Decomposition Theorem
The proof I gave in class was perfectly correct ( except for one minor omission), but the last part was a little bit unclear, and I made it sound more complicated than it really should have been. So let me make the proof completely transparent. Recall that the situation under consideration was this: we had a signed measure ν on a measurable space (X,M). Knowing that such a measure cannot take b...
